A switch running a later IGMP version can identify Report messages of an earlier IGMP version, but the switch running an earlier IGMP version cannot identify Report messages of a later IGMP version. To ensure that IGMP runs properly, you are advised to set the IGMP version on the switch to be the same as or later than the IGMP version of member hosts.
By default, if no router ID is configured but multiple loopback interface addresses are configured, BGP selects the largest loopback interface address as the router ID.
During routine O&M, the administrator checks the IGMP configuration on a router interface. The configuration is as follows:
Interface information of VPN-Instance: public net
GigabitEthernet0/0/1(192.168.1.1):
IGMP is enabled
Current IGMP version is 2
IGMP state: up
IGMP group policy: none
IGMP limit: -
Value of query interval for IGMP (negotiated): -
Value of query interval for IGMP (configured): 60 s
Value of other querier timeout for IGMP: 0 s
Value of maximum query response time for IGMP: 10 s
Querier for IGMP: 192.168.1.1 (this router)
Given this, which of the following statements are true?
In IGMPv1, querier selection depends on a multicast routing protocol, such as PIM. In IGMPv2 and IGMPv3, the interface with the largest IP address acts as the querier.
